Yes physio in warm water is a big help and gentle on bones!
Exercising has definitely helped my back pain but you need to find the source of it first so you don't injure yourself. I work with a trainer who is well trained herself in osteo. We do upper one day and lower the next. I never hurt afterwards. Stay away from the phony trainers who just take you thru a circuit with no clue.
My doctor recommended walking for back pain; I do it every morning and can tell a difference when I miss a day. Seems counter-intuitive but it does work. I also have acupuncture for various aches and pains.
I get lower back pain if I stand alot or have to walk slow, a (having brows walk) I call it
If I sit just as the pain starts it wards of the nasty pains but you need to keep doing this
I also bend my knees and bending from the stomach hold my hands round my calf’s
I have a slip disc in my middle back and lots of silly little things in my lower back
Check with your doctor and ask for. An X-ray if you’ve not had one thou
Lots of things cause lower back pain xxxxxxxxx
Oh and only do what your body will allow xxccc
Merry Christmas xxxxx
